This Report may be used with the public only when preceded or accompanied by
current prospectuses for The Prudential Series Fund, Inc., the applicable
variable life or variable annuity product, and the current Performance Data
Update for the applicable product. The Performance Data Update shows historical
investment performance after the deduction of investment management fees,
investment-related expenses and the product's Mortality and Expense Risk Charge.
For the variable life insurance products, additional contract charges include
the cost of insurance, administrative, sales and any applicable withdrawal or
surrender charges. These charges will reduce the rates of return shown on the
Performance Data Update. For the variable annuity products, the Performance Data
Update provides returns that are net of all contract charges, including
applicable surrender or withdrawal charges. The prospectuses contain more
information concerning charges and expenses, including hypothetical performance
illustrations that show the effects of performance on various assumptions, and
should be read carefully before you invest or send money.

Variable life and variable annuity products are offered by Pruco Securities
Corp., a subsidiary of The Prudential Insurance Company of America. Both are
located at 751 Broad Street, Newark, NJ 07102-3777.

Six Months Ended June 30, 1998

Letter To Contract Owners

President

================================================================================
"Once again, the market reminded us of the critical nature of diversification."

Dear Contract Owner:

We are pleased to provide our Semiannual Report to you on the investment
performance of the portfolios that underlie your Pruco Life Variable Universal
Life variable life insurance contract.

The past six months were a time of slowing economic growth. U.S. Gross Domestic
Product, which measures the country's total output of goods and services, grew
at an estimated annualized rate of 3.5% for the six months ended June 30,
according to Prudential economists.

Given this environment, stock prices continued to gain, with the Dow Jones
Industrial Average rising 13.2% during the six-month period, while the Standard
& Poor's 500 Composite Stock Price Index climbed 17.7%. But, not all stocks were
equal. Large capitalization growth stocks with dependable earnings were the
market's favorites. Indeed, as reported by Morningstar, the average large
capitalization growth fund returned 20.3%, while the average small
capitalization value fund returned 4.7%. Bonds also provided dependable total
returns of 3.9%, according to the Lehman Brothers Aggregate Index.

How Did Our Portfolios Perform?

You will be pleased to learn that the Portfolios of The Prudential Series Fund,
Inc. delivered returns similar to those of the broader markets and consistent
with the strategies around which they were designed. Nearly all of our U.S.
stock portfolios continued to post double-digit returns, while our bond
portfolios finished with very healthy results.

Consistent with the market, our large capitalization growth portfolio -
Prudential Jennison - posted unusually high returns of over 20%. On the other
hand, our value-oriented Equity Portfolio, which returned over 12% in the
six-month period, lagged the growth-oriented fund average. Once again, the
market reminded us of the critical nature of diversification.

Six of our portfolios finished the reporting period ahead of the average
variable life and variable annuity contracts in their respective categories.
These were the Money Market, Diversified Bond, High Yield Bond, Stock Index,
Prudential Jennison, and Global Portfolios.

Fifteen Years and Growing.

The Prudential Series Fund is celebrating 15 years of providing you with the
opportunity to maximize the results of your variable life or variable annuity
contract cash values, subject to the risks associated with these kinds of
investments. As of June 30, 1998, we had assets of $28 billion under management.
We have worked through the years to meet the changing needs of our clients by
increasing from five to 15 the number of investment choices that we believe
offer Contract Owners diversification and the benefits of professional
management. (Not all investment options are available in all contracts.)

Staying the Course for the Long Term.

As we reached the midpoint of another year, the financial news was decidedly
upbeat. However, there were times during the reporting period when price
volatility affected the stock and bond markets. These market swings illustrate
the importance of Contract Owners "staying the course" for the long term.

Of course, this does not mean you should ignore change. Indeed, with record
valuations in the U.S. stock market at a time when U.S. corporate earnings are
slowing, now may be a good time to review your asset allocation. While stocks
continue to be the investment of choice for many seeking long-term wealth
accumulation, you may wish to consider diversifying a portion of your holdings
to help lessen the effects of market uncertainty. Your Prudential professional
would be happy to assist you in reviewing and structuring a program to meet your
needs.

All of us at Prudential thank you for your business and look forward to helping
you plan for your future financial security.

/s/ Jonathan M. Greene                /s/ Mendel A. Melzer

Important Note

The rates of return quoted on the following pages reflect the deduction of
investment management fees and investment-related expenses, but not product
charges. They reflect the reinvestment of dividend and capital gains
distributions. They are not an estimate or a guarantee of future performance.

Contract unit values increase or decrease based on the performance of the
Portfolio and, when redeemed, may be worth more or less than their original
cost. Changes in contract values depend not only on the investment performance
of the Portfolio but also on the insurance and administrative charges,
applicable sales charges, and the mortality and expense risk charge applicable
under the contract. These contract charges effectively reduce the dollar amount
of any net gains and increase the dollar amount of any net losses.

Your Prudential Representative/Pruco Securities Registered Representative can
provide you with actual rates of return for your type of variable life insurance
or annuity contract and show you a personalized illustration of how insurance
charges affect the returns you experience.

1998 Market Review

================================================================================
How the Markets Compared(1)

   [THE FOLLOWING TABLE WAS DEPICTED AS A BAR CHART IN THE PRINTED MATERIAL.]

                                          Average Return Over
                      Return Over            Past 20 Years
                    Past 12 Months           (Annualized)
                    --------------           ------------
Money Market              5.0%                    7.7%
Bonds                    11.3%                   10.0%
Foreign Stocks           17.5%                   15.4%
U.S. Stocks              30.2%                   17.4%

- --------------------------------------------------------------------------------
This chart compares the 12-month return as of 6/30/98 for various categories of
investments with the average annual total return over 20 years for the same
investment. As you can see, stock and bond market returns can vary considerably
from year to year. Unlike stocks, bonds generally offer a fixed rate of return
and principal if held to maturity. An investment's past performance should never
be used to predict future results. There are different risks associated with
each investment sector, which should be carefully considered before investing.

      U.S. money markets as measured by Lipper Money Market Average. Bonds as
      measured by the Lehman Brothers Gov't. Corp. Index. Foreign stocks as
      measured by the Morgan Stanley Capital International World Index. U.S.
      stocks as measured by the S&P 500 Index.

The U.S. Market Only Pauses for Breath.

It was a "flight to quality," but what a flight! The flow of money into the
stock market continued to be strong, bolstered by the record $29 billion influx
from foreign investors in the first quarter. U.S. stocks rose 17.7% year-to-date
as measured by the Standard & Poor's 500 Index (S&P 500), an unmanaged index
considered to be generally representative of the U.S. stock market. It was a
blistering pace.

The economic slowdown in Asia, as well as the release of some disappointing
earnings announcements, gave investors pause from mid-March to mid-June, when
the bull market resumed.

In general, investors preferred growth stocks of large, well-established
companies during the reporting period. Small-company stocks trailed
large-company stocks, while growth stocks dramatically outperformed value
stocks. The differences were substantial.

The market rise has been very focused. Today, the 20 largest growth stocks
represent nearly 30% of the S&P 500, close to the market concentration peak in
1974. The average P/E of these 20 stocks is 36.4, compared to a P/E of 21.3 on
the other 480 stocks in the S&P 500.

Consumer Cyclicals Led.

The best-performing sector in the S&P 500 was consumer cyclicals. These are
companies whose sales to consumers increase when the economy grows. This sector
was led by apparel retailers (up 56%), automobile companies (up 51%) and general
retailers (up 51%) such as Wal-Mart and Kmart. Consumer confidence was high,
interest rates were low and home building got a quick start because of a mild
winter. Home builders (up 31%) also had good returns, although not quite at the
pace of the market leader.

Technology Stocks Were Investors' Favorites.

Manufacturers of communications equipment were the single best-performing group
(up 62%) in the S&P 500. Lucent Technologies' stock more than doubled in price
during the half-year. Computer software companies, such as Microsoft, Computer
Associates, Oracle and Unisys (whose stock also more than doubled in the
period), had the fifth highest average return -- 45%.

Consumer Growth Was Strong.

The consumer growth and staples category includes companies whose sales to
consumers tend to grow at a relatively consistent pace. It was led by restaurant
companies (up 37%), such as McDonald's and TRICON Global Restaurants. Cosmetics
and health-care companies also had a good half-year, but tobacco companies were
the second worst-performing group, losing ground over the period.

Industrials Lagged.

Industrials suffered, because the Asian economic slowdown reduced the demand for
commodities. Railroads (down 11%), specialty chemicals, metals (particularly
aluminum and nonferrous metals) and gold all fell in price.

Energy Demand Lagged.

The economic slowdown in Asia and the mild North American winter, together with
supplies that had been increasing for some time, combined to keep energy firms
at the bottom of the list. Oil and gas drillers was the worst-performing
industry group in the S&P 500.

U.S. Bonds: The Leader of the Pack.

Contrasting economic conditions between the U.S. and Asian countries enhanced
the appeal of U.S. bonds. As a result, the high yield, corporate and government
sectors of the domestic debt market provided the highest returns in the taxable
fixed-income universe over the past six months.

In the U.S., a nearly ideal economic climate prevailed, pushing bond prices
higher and yields lower. Inflation, the archenemy of bondholders, remained
subdued. Economic growth began slowing from the robust 5.4% annualized pace of
the first quarter, indicating that inflationary pressures will likely remain in
check.

Across the Pacific, however, the Japanese economy fell into recession. Skittish
overseas investors shifted money from emerging markets and Asia into U.S.
government securities for their relative safety, causing further declines in
interest rates.

Bonds returned 3.9% for the six-month period ended June 30, 1998, as measured by
the Lehman Brothers Aggregate Index. High yield bonds returned 4.5% for the same
period; U.S. government securities, 4.2%; and investment-grade corporate bonds,
4.2%.

The top performance by corporate high yield (or junk) bonds masked the fact that
the sector fared better in the first quarter than the second quarter. Initially,
strong investor demand easily absorbed the flood of new high-yielding bonds. But
as corporate default rates edged higher and earnings growth slowed, investors
demanded a larger reward for purchasing below investment-grade debt. This
attitude caused the difference between yields on high yield bonds and comparable
Treasuries to increase during the spring.

Investment-grade corporate bonds followed a similar path. Favorable domestic
economic conditions buoyed the market earlier in the year, but continued heavy
new issuance and growing concern about corporate earnings crimped the rally in
late spring.

Among U.S. government securities, longer-term bonds gained most. The yield on
the 30-year Treasury bond fell in June to its lowest level since regular sales
of the securities began in 1977. Tax-exempt municipal bond issuance soared as
state and local governments rushed to take advantage of rock-bottom interest
rates.

The World: Europe Takes Off.

Europe, where stock markets took off a year ago, hit the afterburners in 1998,
returning nearly 27% during the first half of the year in U.S. dollars, as
measured by the Morgan Stanley Capital International (MSCI) Europe Index. This
was more than the MSCI Europe Index's return for all of 1997. The combination of
low interest rates, economic acceleration, the potential productivity gains from
monetary union and increasing participation in stock ownership pushed share
prices up sharply.

France and Germany, the large central economies with the greatest inertia, have
built up steam, turning in returns of 39% and 37%, respectively, for the first
half of 1998. They outpaced the 33% return of Italy, but Spain's stock market
returns continued to lead the larger economies, with a 45% performance. Only
Norway, among the European countries, didn't participate in the bull market,
declining 4% during the past six-months.

Asian and Emerging Markets Faltered.

The Asian financial crisis showed no signs of recovery during the second
quarter. As economic activity slowed, governments wrestled with the structural
changes necessary to restore confidence. Japan, which has the economic heft to
initiate a significant positive change in the region, failed to take any
effective action. Instead, its own economy began to shrink rapidly; its stock
market declined 3% in U.S. dollars through the second quarter. Singapore and
Hong Kong saw greater market erosion, losing 34% and 26%, respectively, during
the same period.

Stock markets at the epicenter of the Asian crisis reflected investors' complete
loss of confidence: Thailand's market fell 56%, Malaysia's 59% and Indonesia's
37%, for the year-to-date period ended June 30, 1998.

The aversion to emerging markets also spread beyond Asia. Taiwan's much sounder
economy had a stock market decline of 24%. Even Latin American countries were
affected, with Mexico down 14%, Brazil down 15% and Argentina down 16%.

Investment capital moved from areas with uncertain economic prospects to what
appeared to be more secure havens as exchange rate adjustments made Latin
America less competitive compared with Asia.

1998 Investment Advisor's Outlook

Market Outlook: Expect Slower Growth.

o Prudential's economists note that the sharp economic acceleration in the first
  quarter of 1998 was due to a buildup of inventories. They expect a sharp
  slowdown in economic activity over the second half of the year as inventories
  are drawn down, net imports increase and greater unused industrial capacity
  slows business investment.

o Inflation has been subdued and should remain so. Although profits have been
  declining in many industries, they believe profits will be squeezed further
  rather than lead to price increases, because businesses face tremendous
  pressure to maintain prices.

o With recent renewed uncertainty in emerging markets and the U.S. manufacturing
  sector now feeling the negative impact of the strong dollar and the downturn
  in Asia, the Federal Reserve is likely to continue to keep policy on hold for
  the next several months. By the fourth quarter of this year, they expect the
  slowdown in the U.S. economy will prompt the Federal Reserve to ease monetary
  policy.

U.S. Stocks: Prices Remain High.

Profit margins are at record levels, and investors are paying record multiples
of these earnings for stocks. However, corporate earnings growth has slowed and,
in many industries, reversed, while the prices of large-company stocks have
continued to rise. Most investors appear to be buying a growth trend, rather
than foreseeable earnings. For some time we have not expected share price gains
to continue at the rate they have. Investors showed some concern during much of
the second quarter about future earnings. We expect them to react to the slowing
U.S. economy by continuing to focus on companies with more predictable earnings.
We see no reason for the market's focus to broaden before prices peak.

We believe that small-company stocks represent better value. Their earnings
growth has been holding up, while their share prices have not kept pace with the
market leaders. This has resulted in price to earnings ratios that are lower for
small-company stocks than for large companies, a very unusual relationship.

Ordinarily, we would expect investors to discover the greater investment values
that small-company stocks now represent and for small caps to catch up. However,
the greater proportion of new investors in the market and the recent flow of
foreign capital to U.S. markets suggest that many current investors may feel
uncomfortable with any but the most familiar stocks. Moreover, small companies
are more vulnerable to a market downturn. In the current market environment, we
are unable to find a catalyst to unlock the superior value offered by
small-company stocks.

Foreign Stocks: Asian Fallout Continues.

The impact of the Asian economic slowdown is gradually being felt throughout the
world. In the U.S. and Europe, it appears to have kept inflation in check. But
it is also making life more difficult for emerging economies.

Although prices in these markets are getting very cheap, we believe it is still
necessary to be very cautious in any of these stock markets. The Japanese
economy is undergoing a sharp contraction. We don't believe that the
government's current actions (a fiscal stimulus package and moderate tax cuts)
will be sufficient to reverse their economic slide or prevent a further decline
in the yen.

Continental Europe is seeing both an economic and a stock market resurgence.
Although share prices have become high by historical standards, prospects for
earnings growth are excellent and better than anywhere else. We expect current
trends to continue.

U.S. Bonds: Treasuries Still Look Good.

We believe the rally in Treasury securities has not run out of steam. Signs of
slower U.S. economic growth have emerged, most notably in the manufacturing
sector.

Separately, the Treasury Department announced plans to meet the government's
reduced borrowing needs by eliminating sales of its three-year notes and cutting
the frequency of five-year note auctions to quarterly from monthly. Taken
together, the Asian financial crisis, moderating U.S. economic growth and the
dwindling supply of Treasury issues will likely lead to higher bond prices and
lower yields.

We will proceed with caution when purchasing bonds during the remainder of the
year. While junk bonds, municipal securities, investment-grade U.S. corporate
debt, global bonds, emerging market bonds, and mortgage-backed and asset-backed
securities still offer solid value, prudence demands we emphasize larger bond
issues that can be easily bought and sold even if prices turn lower.

Additionally, we will even be more reliant upon thorough market research, which
is key to ensuring the overall credit quality dynamic in the portfolios.

A Reality Check.

Stock prices in general have doubled in the last three and a half years. We're
quite pleased with the unusually high returns that stocks have provided for our
Contract Owners over the past few years and we are certain that you are too.
Those types of returns bring you closer to your goals of financial security
faster than you might have expected.

Since 1927, the U.S. stock market's average return has been 10.7%, as measured
by the S&P 500. Yet in recent years returns have been much higher, as the chart

Prudential Money Market Portfolio

Performance Summary.

Your Portfolio returned 2.66% during the six-month reporting period, which
outperformed the 2.54% reported by the average money market fund as tracked by
Lipper Analytical Services. On June 30, 1998, the Portfolio's seven-day yield
was 5.28%, down from 5.61% on December 31, 1997.

The Portfolio was able to benefit from surges in the demand to borrow funds that
temporarily drove short-term interest rates higher. During those times, we moved
quickly to lock in attractive yields and position the Portfolio advantageously,
given that monetary policy held steady throughout the first half of the year.

An investment in the Money Market Portfolio is neither insured nor guaranteed by
the U.S. government. There is no guarantee that the Portfolio will be able to
maintain a stable share value of $10.

Investment Goal

Current income, stability of capital and maintenance of liquidity.

Types of Investments

Short-term money market securities that generally mature in 13 months or less.
These securities primarily consist of Certificates of Deposit (CDs), Commercial
Paper and Bankers' Acceptances, U.S. Treasury bills (T-bills) and other
instruments issued by or guaranteed by the U.S. government or its agencies.

Performance Review.

Rates Edged Lower. During the first half of 1998, money market interest rates
generally hovered at lower levels compared with the second half of 1997.

Belief that the U.S. economic expansion is bound to slow has helped keep a lid
on rates this year. For example, the 12-month London Interbank Offered Rate
(LIBOR) averaged 5.80% during the first half of 1998 compared with 6.00% for the
second half of 1997. This trend was reflected in the decline in the Portfolio's
seven-day yield.

Strategy Session.

Shifting Sand. Market sentiment shifted several times over the past six months
as investors tried to gauge how much Asian financial woes would affect U.S.
economic growth. As the new year began, many investors believed the Asian
financial crisis would slow U.S. economic growth enough that the Federal Reserve
would lower the federal funds rate (the rate banks charge each other for
overnight loans) to stimulate the economy. Market sentiment was so strong that
investors initially drove money market yields lower.

As it turned out, the economy sped along at a 5.5% annualized pace in the first
three months of 1998.

Investors, thinking that such a powerful economy might continue to grow rapidly
despite Asian problems, now believed a federal funds increase might be
necessary. This pushed longer-term money market yields higher in late February
and early March.

Fire Sale Prices. The spring, however, brought another change in market
sentiment. Renewed concern that Asian difficulties could hurt the U.S. economy
caused speculation about a federal funds rate increase to fade in the spring.
This realization kept money market yields in a narrow trading range for the most
part, neither moving dramatically higher nor lower.

In addition, the U.S. Treasury continued paying off debt, keeping a lid on
short-term interest rates by lowering the supply of Treasuries. Under these
conditions, the best buying opportunities emerged at the end of the first and
second quarters when concurrent factors briefly pushed up yields so that money
market securities traded at "fire sale" prices. We purchased three-month and
one-year securities that extended the Portfolio's weighted average maturity.

Outlook

PORTFOLIO MANAGER
Manolita Brasil

A Balanced Perspective.

"The U.S. manufacturing sector may have finally begun to experience the
long-awaited slowdown due to the Asian economic crisis. If the U.S. economy
moderates to the extent expected by the Federal Reserve, monetary policy will
likely remain unchanged in coming months. Of course, if more signs of slower
growth emerge, speculation about a possible federal funds rate cut is bound to
grow. We, however, will be careful to position the Portfolio conservatively to
any overblown swings in market sentiment that arise later in the year."

Prudential Diversified Bond Portfolio

Performance Summary.

Investors fleeing deteriorating economic conditions in Asia purchased U.S.
Treasuries, which are considered to be among the world's safest investments. We
increased your Portfolio's exposure to Treasuries and cut back on long-term
bonds of domestic companies and emerging market governments and corporations. As
a result, the Portfolio's six-month return of 4.44% was greater than the 4.15%
gain of the Lipper (VIP) Corporate Debt Average.

Besides the larger allocation to Treasuries, the surge in mergers and
acquisitions in the U.S. also boosted Portfolio returns. Several of our bonds
rallied after the announcement of key acquisitions in the cable television and
technology sectors.

Investment Goal

High level of income over the long term while providing reasonable safety of
capital.

Types of Investments

U.S. government securities, mortgage backed bonds, both investment-grade and
high yield ("junk bond") corporate debt, and foreign securities (dollar and
non-dollar denominated).

Investment Style

This Portfolio seeks the highest yield while maintaining safety of capital, by
strategically allocating Portfolio assets among the above classes of bonds.

Performance Review.

Spotlight on Asia. Unsettled economic conditions in Asia dominated the
fixed-income markets during the past six months.

The failure of Hong Kong's largest investment bank and a tumbling Japanese yen
were two of the developments that bolstered the appeal of U.S. government
securities. Therefore, increasing the Portfolio's holdings of Treasuries worked
well.

We own debt securities from the cities of Moscow and St. Petersburg in Russia.
Mounting economic problems in Russia pressured the nation's currency, stocks and
bonds. However, the short-term maturities of our Russian assets limited their
price declines.

Strategy Session.

No Quick Fix for Asia. Some investors hoped for an early resolution to the Asian
economic crisis. Confidence was so high that $4 billion of South Korean
government bonds sold in April met with strong investor demand and Asian debt
rallied. We took advantage of this trend to reduce the Portfolio's emerging
markets bond holdings.

Investors eventually realized there would be no quick fix for the Asian crisis.
The Japanese economy is in recession, casting doubt on regional prospects for
recovery anytime soon. In June, the Japanese yen tumbled to an eight-year low
against the U.S. dollar, boosting demand for dollar-denominated assets. Not
surprisingly, Treasuries maturing in 20 years or more gained 6.72% over the past
half-year, as reported by Lehman Brothers. Treasuries climbed to about 21% of
our total investments as of June 30 from 2.0% on December 31, 1997.

Demand Drives Down Yields. Surging demand drove 30-year Treasury bond prices
higher, while the yield fell in June to its lowest level since 1977. With yields
hovering near rock bottom, investment-grade corporate bond issuance soared to
$155.9 billion over the past six months, according to Lehman Brothers. This
flood of debt met with tepid demand in late spring, particularly for longer-term
bonds. Fortunately, we had shifted away from this sector toward short- and
intermediate-term corporate bonds. Our Tele-Communications Inc. bonds rallied
after AT&T announced plans to buy the company, and we sold Digital Equipment
bonds at a profit to Compaq Computer, which acquired Digital.

Outlook

PORTFOLIO MANAGER
Barbara Kenworthy

Caution Is a Virtue.

"We plan to stick with a more cautious approach to investing for the remainder
of the year. We now hold fewer higher-risk assets such as junk bonds and
emerging markets debt. Our shift toward short- and intermediate-term corporate
bonds is yet another example of protecting the Portfolio, since prices of
longer-term bonds would suffer the largest declines if fixed-income markets
turned lower.

"We are keeping a close watch on issuance of junk bonds and investment-grade
corporate bonds, which are on track to break new records in 1998. On the one
hand, this big supply will likely provide great buying opportunities. On the
other hand, the difference between yields on Treasuries and comparable high
yield or junk bonds and investment-grade corporate bonds could increase
significantly if investors balk at purchasing new bonds in the second half of
the year. Treasuries could probably perform better than both junk bonds and
investment-grade corporates in a bond market rally."

Prudential Conservative Balanced Portfolio

Performance Summary.

Your Portfolio returned 8.02% for the first half of 1998, between the 17.72%
return on U.S. stocks and the 4.17% returned by Gov't./Corp. bonds.

Your Portfolio -- which invests in a conservative mix of stocks, bonds and money
market securities -- returned less than the average Flexible (VIP) Portfolio
tracked by Lipper Analytical Services, because the Portfolio's conservative
mandate requires a smaller proportion of equities in the asset allocation.

Investment Goal

Favorable total return consistent with a more conservatively managed diversified
portfolio.

Types of Investments

Money market instruments, bonds and common stocks of both established and
smaller companies.

Investment Style

The Portfolio management team holds a baseline allocation of 35% stocks, 35%
bonds and 30% money market instruments.

Performance Review.

Defensive Positioning. We began the year with part of our stock allocation in
growth stocks, which moved up sharply through the second quarter, contributing
to a strong overall stock contribution. However, we reduced our exposure to
these growth stocks with the aim of improving the stability of our return over
the long run. Our gains slowed with the overall slowing of the market. Our value
stocks, which included some mid-size and smaller firms, were generally out of
favor through the half-year. The inexpensive industrials that were one focus of
our value holdings remained unpopular, although the consumer stocks that were
another focus did provide a strong return.

The Portfolio's bond holdings outpaced the broader bond market, aided by good
credit selection and a rebound in the value of depressed bonds in emerging
markets.


                                       14

Strategy Session.

We Increased Stocks. Although we viewed the equity market as somewhat
overvalued, we believed our stock selection sufficiently conservative that we
allowed our equity allocation to hover near, or slightly above, our normal
level. Our stock holdings are currently close to 40% of our assets.

Aided by a sizable exposure to outperforming growth stocks, the Portfolio's
stock holdings performed better than the S&P 500. In the second quarter, we
invested a sizable portion of the Portfolio's stock holdings into a portfolio
designed to mimic the performance and risk characteristics of the S&P 500 Index.
We expect that this change should bring greater stability to overall Portfolio
performance.

The remaining portion is invested in stocks we believe to be less expensive than
the average stock in relation to their potential earnings. Historically, such
value stocks have had less room to decline in falling stock markets.

We began the period with a focus on corporate and foreign bonds, which enhanced
the return of our bond portfolio early in the period. We had substantially
reduced our holdings when the market turned against them in June. Looking
forward, our bond holdings modestly overrepresent corporate bonds.

Outlook

PORTFOLIO MANAGER
Mark Stumpp

Why Employ a Passively Managed Core Equity Portfolio?

"We believe that investors expect a balanced fund to provide a broad exposure to
investments in several asset classes. With that in mind, we have invested about
one-half of our stock allocation in a core holding that is designed to closely
track the performance of the S&P 500. In our opinion, this should increase the
diversification of the overall equity portfolio and offer an opportunity to
reduce the overall volatility of Portfolio return. By combining a broadly
diversified core holding with an actively managed portfolio, investors should
expect to participate in the overall stock market, and yet will retain the
ability to outperform through active management."

Investment Goal

High total return consistent with a more aggressively managed diversified
portfolio.

Types of Investments

Money market instruments, bonds and common stocks of both established and
smaller companies.

Investment Style

The Portfolio management team holds a baseline allocation of 60% stocks and 40%
bonds.

Performance Review.

Not Joining the Chase. Our bond holdings and our core stock holdings performed
well over the half-year. Aided by an exposure to growth stocks in the first
quarter, the Portfolio's stock holdings performed better than the S&P 500.

However, the contribution of our stocks was constrained by the generally weak
performance of any but large-company growth stocks and by our holdings of
industrial companies. The return of the overall stock market was concentrated in
a few very large companies. As investors focused on these stocks, their prices
rose to unusual levels in comparison with their earnings.

Throughout the six months, we had a substantial portion of our stock allocation
invested in a price-sensitive manner that avoided such companies.

Strategy Session.

Seeking Greater Stability. In the second quarter, we invested a sizable portion
of the Portfolio's stock holdings into a portfolio designed to mimic the
performance and risk characteristics of the S&P 500 Index. We expect that this
change should bring greater stability to overall Portfolio performance.

The remaining portion is invested in stocks we believe to be less expensive than
the average stock in relation to their potential earnings. Historically, such
value stocks have had less room to decline in falling stock markets.

Although we have maintained a slight underweighting in stocks, we have been
buying on market dips and selling into strength. We remain concerned about the
prospects for U.S. corporate profits as the Southeast Asian financial crisis
begins to hit export-oriented business. Stock analysts have significantly
reduced estimates for 1998 corporate earnings and, if current trends persist,
corporations will end the year with earnings only slightly ahead of last year's
levels.

We began the period with a focus on corporate and foreign bonds, which enhanced
the return of our bond portfolio early in the period. We had substantially
reduced our holdings when the market turned against them in June. Looking
forward, our bond holdings modestly overrepresent corporate bonds.

Outlook

PORTFOLIO MANAGER
Mark Stumpp

Why Index?

"We believe that investors turn to a balanced fund primarily for consistency of
returns. With that in mind, we have invested part of our stock allocation in a
core holding that is designed to mimic the performance of the S&P 500. Although
growth stocks have had a strong half-year, their performance has been
concentrated in the gains of a few market leaders. Should the earnings of these
companies stumble, a growth portfolio would be vulnerable. We expect the S&P 500
as a whole to offer more consistent growth in the long run. We believe that
taking that as a target for our core holdings is a conservative strategy well
suited to balanced fund investors."

Prudential High Yield Bond Portfolio

Performance Summary.

Issuance of high yield bonds (also known as junk bonds) surged over the past six
months as corporations rushed to take advantage of lower borrowing costs. This
heavy supply met with tepid demand in the spring, causing junk bonds to cheapen
relative to comparable U.S. Treasuries.

However, your Portfolio's semiannual total return of 5.20% beat the 4.58% gain
on the average high yield fund tracked by Lipper Analytical Services, partly
because of our investment in cable television bonds, one of the best performing
sectors of the high yield market. We also booked profits on some of our health
care and lodging bonds, which were retired early by several companies within
those industries.

Investment Goal

High total return.

Types of Investments

Primarily non-investment-grade bonds. These bonds have speculative
characteristics and are subject to greater credit and market risk than
higher-quality securities.

Investment Style

Concentrates primarily on junk bonds that appear to offer an attractive
combination of high current income and attractive total return.

Performance Review.

Research Is Key. The high yield bond market continues to grow at an explosive
pace, with 1998 on track to surpass last year's record issuance of $111 billion.

As the size and popularity of the high yield bond market increase, we more than
ever rely on in-depth credit research to weed out bonds that will likely run
into trouble in the future.

Thus, our team of research analysts plays an important role in helping your
Portfolio continue to provide solid returns by avoiding future credit quality
problems.

High Yield Bonds Led. High yield bonds provided a 4.50% semiannual return that
led all other sectors of the taxable bond market, based on Lehman Brothers
indexes. Still, the second quarter proved rather challenging for the high yield
bond sector.

With long-term interest rates hovering near rock-bottom levels in the U.S.,
corporations hurriedly issued bonds to lock in low borrowing costs. This flood
of below investment-grade debt securities was easily absorbed initially. But as
corporate default rates edged higher and earnings growth slowed, investors began
to demand a greater reward in the spring for taking a chance on high yield
bonds. As a result, the difference between yields on junk bonds and comparable
Treasuries increased.

Your Portfolio performed well, because we maintained a larger-than-average
exposure to the cable television industry, where debt issuance was rather
limited. In addition, news that AT&T plans to buy Tele-Communications Inc.
boosted prices of cable television bonds, because investors expect more mergers
and acquisitions.

Apart from this trend, your Portfolio benefited when some health care and
lodging companies reduced their borrowing costs by replacing older bonds having
higher interest rates with new bonds that carried lower interest rates. We owned
some of the older bonds that were retired early at prices above their maturity
and current market values, allowing us to realize solid profits.

Outlook

PORTFOLIO MANAGER
George W. Edwards, CFA

Slowdown Warrants Cautious Stance.

"The new issue calendar for high yield bonds remains substantial, and we will
keep a close watch for attractive buying opportunities. However, we worry that
the anticipated slowdown in U.S. economic growth could hurt the ability of
companies in the more cyclical industries, such as steel, technology,
commodities, paper and chemicals, to comfortably pay interest and principal on
their bonds. We therefore are maintaining a below average exposure to bonds of
cyclical industries."

Prudential Stock Index Portfolio

Performance Summary.

Your Portfolio finished the first half of 1998 with a return of 17.48%. The
market began to rise rapidly the second week in January and continued into
March. Renewed concerns about the impact of the Asian economic slowdown
suspended the climb until the last two weeks in June, after companies that were
going to announce lower second-quarter earnings were likely to have done so.

The U.S. economy rose briskly in the first quarter, but borrowed some of that
growth from the second quarter in the form of higher inventory levels. As we go
to press, there are indications that the economy slowed in the second quarter.
Stock market advances were concentrated among the 50 largest companies.

Standard & Poor's neither sponsors nor endorses the Stock Index Portfolio.
Investors cannot directly invest in any index, including the S&P 500.

Performance Review.

The Stock Index Portfolio attempts to hold all 500 stocks included in the S&P
500 Index and to duplicate its performance. Portfolio manager John W.
Moschberger manages the Portfolio by investing funds received while trying to
minimize commissions and transaction costs.

Consumer Cyclicals Led the Way. The market was led by the stocks of companies
selling products that consumers buy more of when the economy is growing. These
consumer cyclicals, notably auto manufacturers and retailers, gained 35% in the
half-year. Technology stocks rose 28%, marking the second highest return.
Computer software companies and communications equipment manufacturers performed
particularly well, while the stocks of Dell, Apple, Lucent and Unisys led the
market, more than doubling in six months.

Consumer Growth Stocks Were Impressive. The sectors in the middle of the pack
also showed impressive returns. Consumer growth and staples stocks, such as
restaurants, cosmetics and pharmaceuticals, averaged a 17% return, while
financials turned in a 16% gain. Whereas companies selling to consumers had
strong stock performance, the industrial companies -- particularly railroads,
metals, specialty chemicals and forest products -- had a very weak second
quarter, actually declining in price on average. Nonetheless, the sector
produced a 12% gain for the half-year, because the market rose rapidly when it
was rising. The utilities sector, which also had a negative second quarter,
recorded an 11% gain for the half-year, an excellent return compared with
historical averages.

Energy Stocks Were Weak. The energy sector brought up the rear for the first six
months of 1998, with almost a 5% gain. Weakened demand because of the Asian
economic slowdown and a warm North American winter combined with growing
supplies to provide a very poor environment for energy companies.

Outlook

PORTFOLIO MANAGER
John W. Moschberger

Keep Your Expectations Realistic.

"In economic uncertainty, investors from around the world find relative
stability in the U.S. S&P 500. Although earnings of these companies have been
growing over the past few years, demand for their stocks has driven share prices
up even faster. Our Stock Index Portfolio is one way to own a cross-section of
U.S. industries, but we do not believe that stock prices can outpace earnings
growth indefinitely. Moreover, earnings growth has slowed and earnings even have
declined in some industries. Despite recent history, investors should not expect
double-digit half-years for stock price growth as a matter of course."

Prudential Equity Income Portfolio

Performance Summary.

Over the past six months, your Portfolio returned 9.90%. Although high by
historical standards, our return trailed that of the Lipper (VIP) Equity Income
Average, because the stock market advance was concentrated in a small group of
very large company growth stocks.

Investors preferred growth stocks regardless of company size. Consequently, our
value stocks did not keep up. Nor did the stocks of mid-sized companies, which
are also well represented in your Portfolio. Our approach is focused on the long
term, though, and has produced returns that have outpaced the Lipper (VIP)
Equity Income Average over the one-, three-, five- and ten-year periods.

Investment Goal

Current income and capital appreciation.

Types of Investments

Primarily stocks and convertible securities with prospects for income returns
above those of the S&P 500.(3)

Investment Style

The Portfolio uses a "value" investment approach to companies that are
attractively priced relative to book value, earnings, discretionary cash flow,
sales and other measures of value.

Performance Review.

Investors Favored Growth Stocks. They preferred not only large-company stocks
but the stocks of the very largest companies during this period. Both trends
worked against us.

Our return also was held back by our focus on industrials -- forest products,
chemicals and metals --- and by our energy and real estate stocks.

Financial Services Helped. Our focus on financial service stocks, including our
large position in Lehman Brothers (up more than 50% in the six months), made a
strong contribution to our return.

Our performance also was supported by our strong focus on economically sensitive
consumer stocks -- autos, retailers and housing-related companies.

Strategy Session.

Cyclicals Are Inexpensive. We believe stocks of companies that do well in an
economic expansion are currently underpriced, because of the extraordinary
length of the U.S. economic expansion and the threatened impact of the Asian
slowdown.

We have focused on two groups of cyclicals: consumer and industrial. Stocks of
companies selling to consumers, such as auto companies, retailers and home
builders, are doing well. Industrials, such as metals, chemicals and forest
products, are languishing. At their current prices, we think both are good
values in a market where value is scarce.

REITs Offer Steady Dividend Growth. Real estate investment trusts (REITs) buy
real estate and issue shares to the public, making it possible to invest in the
burgeoning real estate market by buying a tradable security. Ease of ownership
increases the pool of buyers and should push prices up. We continue to believe
that REITs offer the best prospects for long-term income growth on the market,
well above the average for the S&P 500.

Currently, REITs are selling at very attractive prices compared to other stocks.
We think that investors overreacted to potential legislation that will affect
only a small number of REITs (the paired share trusts) and fear of an overheated
market. We feel that these concerns weren't warranted. We expect our real estate
stocks to rebound and continue their long-term growth.

Outlook

PORTFOLIO MANAGER
Warren E. Spitz

Not a Value Market.

"This is a difficult market for the value style, because most investors appear
to be buying the same few large stocks at any price. For value investors, price
is important. We did not keep up with the market in the first half of 1998,
although our returns are excellent by historical standards. However, since we
haven't been paying top price for our stocks, they have less room to fall when
investors become concerned about profit levels and stock prices peak. The value
style historically has performed well over complete market cycles, and our
Portfolio did exceptionally well in 1997."

Prudential Equity Portfolio

Performance Summary.

Your Portfolio returned 12.47% in the first half of 1998, trailing the Lipper
(VIP) Growth Fund Average of 16.23% for the period.

Stock market performance for some time now has been concentrated in the stocks
of a few very large growth companies. These stocks have been too expensive for
our value style of investing.

While our large weighting in financial services and HMOs helped performance, our
holdings of industrials, smaller electronics companies and tobacco companies
have hurt it. Our large cash position has also reduced performance as stocks
continued to produce returns well above historic averages.

Investment Goal

Capital appreciation.

Types of Investments

Primarily stocks of major, established companies.

Investment Style

This Portfolio uses a "deep value" investment approach to invest in stocks
believed to be temporarily undervalued relative to the companies' sales,
earnings, book value and cash flow.

Performance Review.

Cash Constrains Performance. Our substantial cash holdings remained a constraint
on our return as the market continued to rise rapidly. Nonetheless, our cash is
down from its peak because we found some opportunities when investors became
anxious about the impact of the Asian slowdown. Our time-tested investment
discipline tells us not to buy when prices are high.

We Value Consumer Cyclicals. We have a focus on consumer cyclicals. This was the
best-performing sector of the market. We did particularly well with Chrysler,
Kmart and Tandy.

We also had a focus on financial stocks, such as insurance companies and
financial services. On average, these also had good returns.


                                       24

Strategy Session.

A Hostile Climate for Our Investment Style. Value investing seems to work best
if any of the following conditions exist: The "cheap" stocks are very
inexpensive compared to the average stock; earnings for many businesses are
growing rapidly (earnings growth is abundant, so why pay high prices for it); or
interest rates are high or rising. We've had none of these conditions for some
time now. Investors have picked through the market pretty well and value
differentials are generally small. Profits are slowing -- shrinking, in many
cases, and the Asian economic slowdown has made it difficult for the Federal
Reserve to raise interest rates. As a result, investors have favored the large
companies that generate predictable earnings. So, although our value style is
producing good absolute returns by historical standards, it is trailing the
overall market.

Fear Brings Opportunity. Cyclicals are now among the best value stocks in the
market. We are invested in several cyclical industries: About 7% of our assets
are in paper and forest products companies. Overcapacity in the industry killed
off profits and drove the stocks to historic lows (compared to the overall stock
market). Since then, some capacity has been closed and the industry has begun to
consolidate. We believe the earnings of paper companies have bottomed. The Asian
crisis set back these stocks, because Asia accounts for a third of world paper
demand. However, Asia also accounted for the greatest growth of capacity, which
will slow considerably. The supply/demand situation should improve and we
expect the stocks to rebound.

Our auto companies and retailers, which lost value in the fourth quarter of
1997, recovered in the first half of 1998. Our autos rose 26%, on average, and
retailers were up 23%. Chrysler (up 63%) and Kmart (up 67%) led the way.

Outlook

PORTFOLIO MANAGER
Thomas R. Jackson

Discipline Counts.

"Research shows that it has been wise to stick to an investment style.
Disciplined investors do better in the long run, whatever their style. It is
tough to be a disciplined value investor when other investors are concentrating
almost exclusively on companies that are too expensive for your value style.
However, history demonstrates that economic conditions change and investment
styles come in and out of favor. Meanwhile, as long as the market focuses solely
on this small group of large growth companies, even though a rapidly rising
market may give us a good return, we will lag our more aggressive growth
competitors. Our return relative to other funds shines most when uncertainty
about the economic future leads investors to leave some bargains on the table.
With this in mind, we are sticking to our discipline."

Prudential Jennison Portfolio

Performance Summary.

The stock market notched up another strong half-year of growth. Your Portfolio's
20.75% return was more than four percentage points ahead of the 16.23% gain of
the Lipper (VIP) Growth Average. By owning stocks of companies with predictable
and growing earnings, the Portfolio benefited as investors were willing to pay
more for growth stocks.

Our strong performance was broadly based, with the greatest contributions coming
from pharmaceutical, retail, telecommunications service, financial services and
technology stocks. The primary drag on our return was from companies dependent
on capital spending.

Investment Goal

Long-term growth of capital.

Types of Investments

Primarily common stocks of established companies with above-average growth
prospects.

Investment Style

This Portfolio uses a "growth" investment style to invest in the common stocks
of both mid-size and large companies.

Performance Review.

Drug Stocks Good for Us. Pharmaceutical stocks continue to rise as new product
introductions bode well for earnings growth. Pfizer, Warner-Lambert and Monsanto
(owner of Searle) made the greatest contributions to our return.

Consumers Are Buying. Stocks of retailers generally did very well in the first
half. We benefited particularly from our holdings of Gap stores, Home Depot and
Kohl's (a regional specialty department store company). Increases in reported
same-store sales motivated the gains.

Keeping in Touch. Wireless telecommunications service companies in Europe, as
well as in the U.S., were strong performers in the period. Vodafone, WorldCom
and AirTouch Communications had the greatest impact on our return.


                                       26

Strategy Session.

Uncertain About Technology. There has been a great deal of uncertainty in the
technology sector: inventory corrections in personal computers, pricing pressure
in memory chips and shortfalls in earnings from companies as well known as
Intel, Motorola and Compaq. We reduced our exposure to these companies during
the period.

On the other hand, companies serving the telecommunications, networking and
software sectors made strong contributions to our performance. Wireless
communications and data networking are driving the telecommunications business.
Our holdings in these service providers performed remarkably during the
six-month period, exceeding our most optimistic short-term expectations.

Consolidation Continues in Financial Services. The financial services industry
continues to consolidate: Brokers buy banks, banks buy investment management
companies, insurers buy other insurers. We have a number of holdings in the
Portfolio which should benefit from this phenomenon.

The largest is Citicorp, soon to become CitiGroup. Since the announcement of its
acquisition by Travelers, the stock hasn't performed particularly well, but we
remain optimistic about the intermediate-term outlook.

Outlook

PORTFOLIO MANAGER
David T. Poiesz

Analysis Is Key to Performance.

"For the past six months, the S&P 500 has gained more than 15% -- that's more
than even the most optimistic market-watchers would have foreseen. While we
don't try to predict the market's direction, our Portfolio has been well
positioned for the move. However, corporate earnings disappointments are
increasing. We expect our Portfolio to distinguish itself with its superior
earnings growth. We expect the bulk of that growth to come from holdings in the
health care, telecommunications, technology and financial services sectors, all
rapidly growing areas of the global economy.

"If the Asian downturn slows the European and North American economies too much,
stock prices will reflect the threat of recession. However, we believe our
Portfolio is less economically sensitive than most, because we look for
companies that can increase their earnings predictably. The key to our
performance will continue to be how well we analyze our companies' earnings
growth potential and the degree to which the market values consistent growth."

Prudential Global Portfolio

Performance Summary.

Your Portfolio began 1998 very strongly, returning 19.34% over the first six
months and outperforming the Lipper (VIP) Global Average by a significant margin
over that period.

Our second-quarter return was 3.71%. We had a strong focus on the top-performing
Continental European market, and our stock selection within that market improved
our return. We also largely avoided the very poor stock markets in Asia and
emerging markets.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risk of currency fluctuation and the impact of social, political and
economic change.

*     Lipper provides data on a monthly basis, so for comparative purposes the
      Lipper Average and Index since inception returns reflect the Portfolio's
      closest calendar month-end performance of 9/30/88.

(1)   Past performance is not predictive of future performance. Portfolio
      performance is net of investment fees and fund expenses but not product
      charges. Source: Prudential. Six month returns not annualized.

(2)   The Lipper Variable Insurance Products (VIP) Global Average is calculated
      by Lipper Analytical Services, Inc., and reflects the investment return of
      certain portfolios underlying variable life and annuity products. These
      returns are net of investment fees and fund expenses but not product
      charges.

(3)   The Morgan Stanley Index is a weighted index comprised of approximately
      1,500 companies listed on the stock exchanges of the U.S.A., Europe,
      Canada, Australia, New Zealand and the Far East. The combined market
      capitalization of these companies represents approximately 60% of the
      aggregate market value of the stock exchanges in the countries comprising
      the World Index. The World Index is an unmanaged index that includes the
      reinvestment of all dividends but does not reflect the payment of
      transaction costs and advisory fees associated with an investment in the
      Portfolio. The securities that comprise the World Index may differ
      substantially from the securities in the Portfolio. The World Index is not
      the only index that may be used to characterize performance of global
      funds, and other indexes may portray different comparative performance.

Investment Goal

Long-term growth of capital.

Types of Investments

Primarily common stock and common stock equivalents of U.S. and foreign
corporations.

Investment Style

This Portfolio uses a "growth" investment approach, coupled with a
theme-oriented view of the markets, to identify companies that seem best
positioned to take advantage of global changes.

Performance Review.

In the Right Place at the Right Time. Several different kinds of judgment
contributed to our above-average, six-month performance.

We were in the right places, primarily Continental Europe, and not much in Asia
or emerging markets. We were in the right industries. Our software and
telecommunications stocks had strong returns. Our financial companies in Europe
are riding a wave of industry consolidation, productivity improvements and new
revenue streams from managing investments.

We also picked the right stocks. For example, our Japanese holdings, although a
small part of our Portfolio, performed better than the average Japanese stock.

Strategy Session.

Continental Europe Is the Place to Be. In Continental Europe, economic recovery,
together with many beneficial changes associated with European monetary union,
is creating strong earnings growth. We increased our holdings there, adding to
our financial companies.

Financial firms are benefiting from the expanding economy, the low interest
rates that were a prerequisite for monetary union and a restructuring of
European financial services. They are offering popular new products -- such as
bank-managed mutual funds -- and the industry is likely to consolidate.

Communications Are Happening. We're emphasizing communications across the globe,
broadening our reach from the U.S. We are adding to our television exposure in
anticipation of the introduction of digital broadcasting in the U.K. We're also
adding U.S. media companies.

Asia Is Uncertain. We are cautious and continue to underweight Asia, whose
problems are being compounded by political inaction in Japan. We focused our
Japanese holdings more narrowly on export-oriented industrials and hedged almost
all our exposure to changes in the value of the yen.

Outlook

PORTFOLIO MANAGER
Daniel J. Duane

Europe Is the Place to Be.

"Right now, Europe is the epicenter of world economic growth. Even France and
Germany, which have been overregulated sluggish giants, are beginning to stir.
In the U.S. today, we like the software firms that are benefiting from
productivity trends, the health-care firms that are pioneering the restructuring
of the industry in the U.S., and retailers -- primarily because they benefit
from the long economic expansion and are buffered from the impact of events in
Asia.

"We would have liked to see countries in the Pacific follow the U.S. economic
model: openness to investment and credit decision-making, allowing free markets
to decide how capital is allocated. There is movement in that direction, but
Japan is unfortunately resisting the large-scale restructuring that these
changes would require. The decline of Southeast Asian labor costs and currency
values are creating uncertainties for other emerging markets. We will be very
cautious in investing in the Pacific and in emerging markets until the situation
clarifies."

                      NOTES TO THE FINANCIAL STATEMENTS OF
                             CERTAIN PORTFOLIOS OF
                        THE PRUDENTIAL SERIES FUND, INC.
                                  (UNAUDITED)

NOTE 1:  GENERAL

The Prudential Series Fund, Inc. ("Series Fund"), a Maryland corporation,
organized on November 15, 1982, is a diversified open-end management investment
company registered under the Investment Company Act of 1940, as amended. The
Series Fund is composed of fifteen Portfolios ("Portfolio" or "Portfolios"),
each with a separate series of capital stock. The information presented in thse
financial statements pertains to only the ten Portfolios available for
investment by Variable Universal Life: Money Market Portfolio, Diversified Bond
Portfolio, Conservative Balanced Portfolio, Flexible Managed Portfolio, High
Yield Bond Portfolio, Stock Index Portfolio, Equity Income Portfolio, Equity
Portfolio, Prudential Jennison Portfolio and Global Portfolio. Shares in the
Series Fund are currently sold only to certain separate accounts of The
Prudential Insurance Company of America ("The Prudential"), Pruco Life Insurance
Company and Pruco Life Insurance Company of New Jersey (together referred to as
the "Companies") to fund benefits under certain variable life insurance and
variable annuity contracts ("contracts") issued by the Companies. The accounts
invest in shares of the Series Fund through subaccounts that correspond to the
Portfolios. The accounts will redeem shares of the Series Fund to the extent
necessary to provide benefits under the contracts or for such other purposes as
may be consistent with the contracts. The ability of the issuers of the
securities held by the Money Market Portfolio to meet their obligations may be
affected by economic developments in a specific industry or region.

NOTE 2:  ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Series Fund in preparation of its financial statements.

SECURITIES VALUATION:  Securities traded on an exchange (whether domestic or
foreign) are valued at the last reported sales price on the primary exchange on
which they are traded. Securities traded in the over-the-counter market
(including securities listed on exchanges for which a last sales price is not
available) are valued at the average of the last reported bid and asked prices
or at the bid price on such day in the absence of an asked price. Convertible
debt securities are valued at the mean between the most recently quoted bid and
asked prices provided by principal market makers. High yield bonds are valued
either by quotes received from principal market makers or by an independent
pricing service which determine prices by analysis of quality, coupon, maturity
and other factors. Any security for which a reliable market quotation is
unavailable is valued at fair value as determined in good faith by or under the
direction of the Series Fund's Board of Directors.

The Money Market, Conservative Balanced and Flexible Managed Portfolios use
amortized cost to value short-term securities. Short-term securities that are
held in the other Portfolios which mature in more than 60 days are valued at
current market quotations and those short-term securities which mature in 60
days or less are valued at amortized cost.

The High Yield Bond Portfolio may hold up to 15% of its net assets in illiquid
securities, including those which are restricted as to disposition under
securities law ("restricted securities"). Certain issues of restricted
securities held by the High Yield Bond Portfolio at June 30, 1998 include
registration rights, some of which are currently under contract to be
registered. Restricted securities, sometimes referred to as private placements,
are valued pursuant to the valuation procedures noted above.

REPURCHASE AGREEMENTS:  In connection with transactions in repurchase agreements
with U.S. financial institutions, it is the Series Fund's policy that its
custodian or designated subcustodians, as the case may be under triparty
repurchase agreements, take possession of the underlying collateral securities,
the value of which exceeds the principal amount of the repurchase transaction
including accrued interest. If the seller defaults and the value of the
collateral declines or if bankruptcy proceedings are commenced with respect to
the seller of the security, realization of the collateral by the Series Fund may
by delayed or limited. (See Note 5).

FOREIGN CURRENCY TRANSLATION:  The books and records of the Series Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:

(i) market value of investments securities, other assets and liabilities - at
the current rates of exchange.

(ii) purchases and sales of investment securities, income and expenses - at the
rate of exchange prevailing on the respective dates of such transactions.

Although the net assets of the Series Fund are presented at the foreign exchange
rates and market values at the close of the fiscal period, the Series Fund does
not isolate that portion of the results of operations arising as a result of
changes in the foreign exchange rates from the fluctuations arising from changes
in the market prices of securities held at the end of the fiscal period.
Similarly, the Series Fund does not isolate the effect of changes in foreign
exchange rates from the fluctuations arising from changes in the market prices
of long-term portfolio securities sold during the fiscal period. Accordingly,
these realized and unrealized foreign currency gains (losses) are included in
the reported net realized gains (losses) on investment transactions.

Net realized gains (losses) on foreign currency transactions represent net
foreign exchange gains or losses from holdings of foreign currencies, currency
gains or losses realized between the trade and settlement dates on security
transactions, and the difference between the amounts of dividends, interest and
foreign taxes recorded on the Series Fund's books and the U.S. dollar equivalent
amounts actually received or paid. Net unrealized currency gains or losses from
valuing foreign currency denominated assets and liabilities (other than
investments) at fiscal period end exchange rates are reflected as a component of
net unrealized appreciation (depreciation) on investments and foreign
currencies.

                                       88
<PAGE>
 
Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.

SHORT SALES:  Certain portfolios of the Series Fund may sell a security it does
not own in anticipation of a decline in the market value of that security (short
sale). When the Portfolio makes a short sale, it must borrow the security sold
short and deliver it to the buyer. The proceeds of the short sale will be
retained by the broker-dealer through which it made the short sale as collateral
for its obligation to deliver the security upon conclusion of the sale. The
Portfolio may have to pay a fee to borrow the particular security and may be
obligated to remit any interest or dividends received on such borrowed
securities. A gain, limited to the price at which the Portfolio sold the
security short, or a loss, unlimited in magnitude, will be recognized upon the
termination of a short sale if the market price at termination is less than or
greater than, respectively, the proceeds originally received.

OPTIONS:  The Series Fund may either purchase or write options in order to hedge
against adverse market movements or fluctuations in value with respect to
securities which the Series Fund currently owns or intends to purchase. The
Series Fund's principal reason for writing options is to realize, through
receipts of premiums, a greater current return than would be realized on the
underlying security alone. When the Series Fund purchases an option, it pays a
premium and an amount equal to that premium is recorded as an investment. When
the Series Fund writes an option, it receives a premium and an amount equal to
that premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Series Fund realizes a gain or loss to the extent of the
premium received or paid. If an option is exercised, the premium received or
paid is an adjustment to the proceeds from the sales or the cost of the purchase
in determining whether the Series Fund has realized a gain or loss. The
difference between the premium and the amount received or paid on effecting a
closing purchase or sale transaction is also treated as a realized gain or loss.
Gain or loss on purchased options is included in net realized gain (loss) on
investment transactions. Gain or loss on written options is presented separately
as net realized gain (loss) on written option transactions.

The Series Fund, as writer of an option, may have no control over whether the
underlying securities may be sold (called) or purchased (put). As a result, the
Series Fund bears the market risk of an unfavorable change in the price of the
security underlying the written option. The Series Fund, as purchaser of an
option, bears the risk of the potential inability of the counterparties to meet
the terms of their contracts.

FINANCIAL FUTURES CONTRACTS:  A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Series Fund is required to pledge to the broker an amount of cash and/or
other assets equal to a certain percentage of the contract amount. This amount
is known as the "initial margin". Subsequent payments, known as "variation
margin", are made or received by the Series Fund each day, depending on the
daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.

The Series Fund invests in financial futures contracts in order to hedge its
existing portfolio securities or securities the Series Fund intends to purchase,
against fluctuations in value. Under a variety of circumstances, the Series Fund
may not achieve the anticipated benefits of the financial futures contracts and
may realize a loss. The use of futures transactions involves the risk of
imperfect correlation in movements in the price of futures contracts and the
underlying assets.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME:  Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Dividend income is recorded on the
ex-dividend date; interest income, which is comprised of four elements: stated
coupon, original issue discount, market discount and market premium is recorded
on the accrual basis. Certain portfolios own shares of real estate investment
trusts ("REITs") which report information on the source of their distributions
annually. A portion of distributions received from REITs during the period is
estimated to be a return of capital and is recorded as a reduction of their
costs. During the six months ended June 30, 1998, certain Portfolios purchased
securities from and sold securities to other Portfolios of the Series Fund or
other funds or accounts managed by The Prudential or its affiliates in
accordance with the provisions of Rule 17a-7 of the Investment Company Act of
1940. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management. The Series Fund expenses are allocated to the
respective Portfolios on the basis of relative net assets except for expenses
that are charged directly at a Portfolio level.

CUSTODY FEE CREDITS:  The Series Fund, exclusive of the Global Portfolio, has an
arrangement with its custodian bank, whereby uninvested monies earn credits
which reduce the fees charged by the custodian. Such custody fee credits are
presented as a reduction of gross expenses in the accompanying Statement of
Operations.

TAXES:  For federal income tax purposes, each portfolio in the Series Fund is
treated as a separate taxpaying entity. It is the intent of the Series Fund to
continue to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all of its net income to
shareholders. Therefore, no federal income tax provision is required.

Withholding taxes on foreign dividends, interest and capital gains have been
provided for in accordance with the Series Fund's understanding of the
applicable country's tax rules and regulations.

DIVIDENDS AND DISTRIBUTIONS:  Dividends and distributions of each Portfolio are
declared in cash and automatically reinvested in additional shares of the Fund.
The Money Market Portfolio will declare and reinvest dividends from net
investment income and net realized capital gain (loss) daily. Each other
Portfolio will declare and distribute dividends from net investment income, if
any, quarterly and net capital gains, if any, at least annually. Dividends and
distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.

RECLASSIFICATION OF CAPITAL ACCOUNTS:  The Series Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants' Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gains, and
Return of Capital Distributions by Investment Companies. For the six months
ended

NOTE 3:  AGREEMENTS

The Series Fund has an investment advisory agreement with The Prudential.
Pursuant to this agreement The Prudential has responsibility for all investment
advisory services and supervises the subadvisers' performance of such services.
The Prudential has entered into a service agreement with The Prudential
Investment Corporation ('PIC'), which provides that PIC will furnish to The
Prudential such services as The Prudential may require in connection with the
performance of its obligations under the investment advisory agreement with the
Series Fund. In addition, The Prudential has entered into a subadvisory
agreement with Jennison Associates LLC ('Jennison'), under which Jennison
furnishes investment advisory services in connection with the management of the
Prudential Jennison Portfolio. The Prudential compensates Jennison for its
services as follows: 0.75% on the first $10 million of that Portfolio's average
daily net assets, 0.50% on the next $30 million, 0.35% on the next $25 million,
0.25% on the next $335 million, 0.22% on the next $600 million and 0.20%
thereafter. The Prudential pays for the cost of PIC's services, compensation of
officers of the Series Fund, occupancy and certain clerical and administrative
expenses of the Series Fund. The Series Fund bears all other costs and expenses.

The investment advisory fee paid The Prudential is computed daily and payable
quarterly, at the annual rates specified below of the value of each of the
Portfolio's average daily net assets.

Prudential Jennison Portfolio..........             0.60
Global Portfolio.......................             0.75
 
The Prudential has agreed to refund to a Portfolio (other than the Global
Portfolio), the portion of the investment advisory fee for that Portfolio equal
to the amount that the aggregate annual ordinary operating expenses (excluding
interest, taxes and brokerage commissions) exceeds 0.75% of the Portfolio's
average daily net assets. No refund was required for the six months ended June
30, 1998.

PIC and Jennison are indirect, wholly-owned subsidiaries of The Prudential.

The Series Fund has a credit agreement (the "Agreement") with an unaffiliated
lender. The maximum commitment under the Agreement is $250,000,000. The
Agreement expires on December 18, 1998. Interest on any such borrowings
outstanding will be at market rates. The purpose of the Agreement is to serve as
an alternative source of funding for capital share redemptions. The Series Fund
did not borrow any amounts pursuant to the Agreement during the six months ended
June 30, 1998. The Series Fund pays a commitment fee at an annual rate of .055
of 1% on the unused portion of the credit facility. The commitment fee is
accrued and paid quarterly by the Series Fund.
